Title: Improvements in and relating to counter circuits
Filed: 1942-05-06
Abstract: 557,172. Counting-apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). May 6, 1942, No. 6111. [Class 106 (i)] [Also in Group XL] A counter or divider circuit comprises a plurality of discharge devices the last of which serves as an extinguishing device and may not be of the gaseous discharge type. The anode of the initiating discharge device is connected to the anode supply and the succeeding anodes are connected to the preceding cathodes, while the impulses to be counted are applied to the control grids in parallel. In this way the first impulse sets up a discharge in the tube T<SP>1</SP> so that a voltage is produced across cathode resistance R<SP>16</SP> and serves as anode supply to the succeeding tube which sets up a discharge when the second impulse is applied. Premature ignition of the succeeding tube T<SP>2</SP> is prevented by condenser C<SP>6</SP> while resistance R<SP>11</SP> limits the current during the discharge through tube T2. The cathode of the extinguishing tube T<SP>5</SP>, Fig. 1, is coupled to the cathode of the initiating tube T<SP>1</SP> and the time constant of the resistance-condenser combination C<SP>10</SP>, R<SP>15</SP> is small enough to prevent T<SP>1</SP> igniting with T<SP>5</SP> but large enough to extinguish T<SP>1</SP> when T<SP>5</SP> is ignited. Neon tubes 0 ... 4, which may be of the numeral type, and which are connected between the anodes and cathodes so as to be energized only while voltage is applied across this path, indicate the number of pulses applied. Output may be taken from the anode of the tube T<SP>5</SP> or an isolating valve T<SP>6</SP> may be use which will reverse the pulse polarity. The arrangement may serve as a divider and a number of stages in cascade may be used. With a constant frequency source the apparatus may constitute a measuring apparatus for short time intervals or alternatively be used to measure frequency. Fig. 4 shows an arangement in which the extinguishing tube is a vacuum tube, the grid 19 functioning as the anode. A scale-of-two counter, Fig. 5 (not shown) may comprise a gas discharge tube succeeded by a vacuum tube with resistances in each cathode circuit and condenser coupling between the cathodes to prevent premature energization of the vacuum tube.

Title: Sound and vibration damping constructional material
IPC: G10K11/168
Filed: 1967-02-08
Abstract: 1,261,011. Vibration damping. GERMANY DEFENCE MINISTER OF. 8 Feb., 1967 [28 April, 1966], No. 6112/67. Heading F2S. A constructional material damped against the transmission of sound or vibration in tension or compression is formed from a load-bearing material provided with a damping material having inherent loss characteristics, the loadbearing material itself or a covering layer over the load-bearing material comprising recesses filled with the damping material, the recesses being so dimensioned that the change in length occurring in a portion of the material when under tensile or compressive load is substantially confined to a change in length of the recesses which are short compared with the total length of the portion of material. In one embodiment, as shown in Fig. 2, a smooth, for example metallic, loadbearing material 1 is covered with a layer consisting of alternate layers of damping material 2 which may be visco-elastic and relatively long elements 3 of a material having a high modulus of elasticity. The covering layer 2, 3 is covered by a second load-bearing material 5. If the loadbearing materials 1, 5 are only cemented to the covering layer 2, 3, they may be connected by through-going screws, rivets 6 or struts 7. Since the modulus of elasticity of the elements 3, which may be of metal or ceramic, is a multiple of that of the damping material 2, the change in length of the covering layer 2, 3 when the material is loaded by an alternating force (as represented by the double arrow 4) occurs practically only in the thin layers of damping material 2 which are thereby relatively intensely deformed and absorb vibration energy. In an alternative construction, the elements 3 are embedded in granular form in the damping material 2. In the embodiment shown in Fig. 4, the damping material 2 is embedded directly in recesses in the load-bearing material 8. The recesses may be disposed in a row down one side of the load-bearing material 8, as shown, or in a row down the centre of the load-bearing material, or in rows down both sides of the load-bearing material with the recesses of one row opposite or intermediate those of the other row. The load-bearing material may be sheet metal through which slot-shaped recesses extend in the form of apertures and are filled with damping material. The constructional material of this invention has a high damping effect on elongation (longitudinal) waves as well as bending (transverse) waves. Suitable for use as the damping material are commercial materials having inherent loss characteristics and which are generally known as anti-noise substances.

Title: Apparatus for the production of digital signals
IPC: G05B19/25
Filed: 1968-02-07
Abstract: 1,214,169. Programmed control of machine tools. GIDDINGS & LEWIS Inc. Feb.7, 1968 [Feb.28, 1967], No.6139/68. Heading G3N. In an apparatus for the production of digital signals a digital sweep and a sinusoidal signal of the same frequency and predetermined phase, from which is derived a variable phase sinusoidal signal, an applied to a digital register wherein a digital number signal is stored having a value dependent on the phase of the variable phase sinusoidal signal. As shown, a clock pulse train from a generator 32 is applied to a generator 34 producing a digital sweep representing a reference number which changes from a first to a second number by uniform increments. A generator 36 produces a reference squarewave, having a constant phase relative to the cycling intervals of the digital sweep, which is applied to a shaper 38 that converts it to a sinusoid. The reference sine wave is applied on line 13 to the common line of trimming potentiometers 11a to lid to which is also selectively applied, by a selector 56, a quadrature reference sine wave derived from a phase-shifter 40. The sliders of the potentiometers are variable to set the desired phase of the output voltage on lines 59a to 59d selected by the output selector 58 in synchronism with selector 56. The selected phase shifted sine wave is applied over a line 60 to a digital catcher 50 which, in response to the digital sweep from generator 34, produces a digitally signalled number whose value is representative of the phase angle of the potentiometer output. The digitally signalled number is fed to an adder 62 where it is combined with a command number from a source 64, comprising a punched-tape reader, and a corrective constant from a generator 66. The summated output from the adder is fed to data utilization devices 68 such as the controls of a milling machine. A read-out 70 responsive to a control 70a, displays the value corresponding to the potentiometer setting, in order to facilatate adjustment. In a numerical control system for a machine tool, the output of the trimming potentiometers is combined with the sinusoidal position dependent signal from a resolver, not shown, driven by a moving part of the machine tool, in the digital catcher 50.
